V PUMP-BARREL.

To all whom it may concern:

Be it known that I, OLEM WVILLIAMs, a citizen of the United States,residing at Bluffton, in the county of Wells, State of Indiana, haveinvented certain new and useful Improvements in Pump-Barrels; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to improvements in pump barrels and the leadingobject in view is the provision of a pump barrel with a glass lining andpacking means for rigidly holding the lining in place against movementin the pump barrel.

Another object of the invention is the construction of a pump barrelhaving a tubular glass lining inserted therein and sleeves threaded onthe ends of the pump barrel and the glass lining whereby sai ends, areeffectively sealed against leakage of the fluid passing through the pumpbarrel.

WVith the above and other objects in view the invention consists incertain combinations, constructions and arrangements of parts, clearlydescribed in the following specification and clearly illustrated in theaccompanying drawings, in which 2- Figure 1 is a longitudinal centralsectional view through a pump barrel constructed in accordance with myinvention. Fig. 2 is a central longitudinal sectional view of one of theconnectin sleeves.

Referring to file accompanying drawings 5 denotes a pump barrel havingexternal screw threads 6 on its ends. Within the pump barrel 5 a tubularglass lining 7 removably but closely fits, the ends of saidSpecification of Letters Patent. Patented July 11, 1911. Applicationfiled September 23, 1910.

of sections or in a single piece. A sleeve 8 having internal screwthreads is threaded on the end of the pump barrel and said sleeve isformed with an internal circular shoulder 9. An annular packing member10 is disposed against the shoulder 9 and is adapted to be compressedagainst the adjoining ends of the pump barrel 5 and the tubular glasslining 7, by means of the sleeve 8. The sleeve 8 is also formed withinternal screw threads 11 which'may be connected to a second pump barrelsection and a second packing ring may be disposed against the other sideof the shoulder 9 to seal the adjoining ends of the second pump barrelsection and the tubular glass lining inserted therein. The internaldiameter of the shoulder 9 is the same as the internal diameter of theglass lining 7 so the inner peripheral surface 9 will be flush with theinner internal peripheral surface of the glass lining 7 and consequentlythe'resistance of friction of the joint will be very small. Thisarrangement however may be varied if desired so that the shoulder canoverlap the glass lining.

WVhat is claimed is A pump barrel provided with a glass lining closelyand removably disposed therein,

said glass lining having a smooth internal surface and its endsterminating flush with the ends of the pump barrel, a packing ringdisposed against the adjoining ends of the pump barrel and the glasslining, and a connecting sleeve having an internal circular shoulderbearing firmly against the packing ring to seal the adjoining ends ofthe glass lining and the pump barrel, the internal shoulder of thesleeve having the same diameter as the internal diameter of the glasslining whereby little resistance is offered to the flow of liquid.

In testimony whereof, I afliX my signature, in presence of twowitnesses.
